Description
Technical field
This utility model relates to filtering draining slip casting film bag water blockoff hole sealing structure, especially relates to complicated geological Tunnel Engineering
One in field is used for controlling to filter in water fathering slip casting draining slip casting film bag hole sealing structure device.
Background technology
Tunnel construction is fast-developing in southwest, but also runs into the technology of some keys during tunnel construction
A difficult problem, Southwestern China area is the key area that the geology such as Karst Fissures is grown, and taking grouting for water blocking is then to solve crack
Good settling mode, but grouting for water blocking also exists the problem that water blockoff sealing of hole is difficult, and directly resulting in slip casting can not be normally carried out.Main
Problems with to be had: 1. when at hydrous fluids, needs bigger grouting pressure, if boring not strength closure can cause slip casting
It is unable to reach predetermined grouting pressure；The measures such as the expanded rubber plug 2. in the past used or filling Anchor Agent, poor effect is difficult
To bear high pressure；And well can not fit tightly with boring, cause spillage；3. traditional hole sealing device is used to install multiple
Miscellaneous, relatively costly.
Therefore, there is above problem in tradition injection hole sealing constructional device, needs badly and can solve the problem that the problems referred to above in engineering
Constructional device, the newest more effectively, the hole sealing structure device of easy construction meet engineering construction needs.
Summary of the invention
In order to solve during controlling slip casting, the problem that not can solve density difference at water blockoff sealing of hole, causes
Not reaching the grouting pressure of anticipation, the blocking device in the past used is difficult to bear high pressure, it is impossible to well fits with the wall of a borehole, becomes
The problems such as this is higher, devise a kind of for controlling to filter in water fathering slip casting draining slip casting film bag hole sealing structure device, by this
Constructional device can well solve the difficult problem in water blockoff sealing of hole in controlling slip casting at present.
This utility model is a kind of for controlling to filter in water fathering slip casting draining slip casting film bag hole sealing structure device, is by noting
Serous coat bag structure, injected hole, around country rock composition；Wherein slip casting film bag structure is then short by slip casting long tube, slip casting film bag, slip casting
Pipe forms, and slip casting long tube and slip casting short tube are by being weldingly connected.
Being provided with draw-in groove as improvement, slip casting long tube and slip casting short tube, slip casting film bag can be directly fixed on by rib tape
In draw-in groove；On slip casting short tube, draw-in groove top and lower bayonet slot bottom are provided with screw thread；The position that slip casting short tube is covered by slip casting film bag sets
There is stream slurry hole.
As improvement, slip casting film bag is that polyacrylonitrile macromolecular material is made；Slip casting film bag can be carried out according to boring needs
Adjust size and the length of slip casting film bag.
As improvement, by being weldingly connected between slip casting long tube and slip casting short tube, and it is provided with solder side.Stream slurry hole is short in slip casting
Guan Shangcheng plum blossom-shaped arranges.
The beneficial effects of the utility model:
1. using filter draining film bag water blockoff hole sealing structure device, this device can effectively play very in controlling slip casting
Good effect, and simple in construction, with low cost.
2. slip casting short tube injects serosity in slip casting film bag, and water flows away from slip casting film bag, slip casting film bag volumetric expansion with
Hole wall fits tightly, and fast filtering falls the moisture in slurry and hardens, it is achieved good closure.
3. by arrange on the slip casting short tube that slip casting film bag covers stream slurry hole can complete the slip casting to slip casting film bag, side
Method is simple, easily operates；
4. draw-in groove is set on slip casting long tube and slip casting short tube, slip casting film bag can be fixed, and screw thread on slip casting short tube,
Can slip casting solidify after by grouting pressure increasing friction force.
